CHECK- ROWER.

SPECIFICATION forming part of Letters Patent No. 539,915, dated May as,1895.

Application filed December 11, 1894. Serial No. 531,459. (No model.)

ure hereinafter described and it is defined in the appended claims.

In the drawings forming part of this specificatlon, Flgure 1 is a planof check-row mechanism constructed in accordance with my invention. Fig.2 is an elevation of the center movement of the check-rower from theposition indicated'by arrow X, Fig. 1. Fig. 3 is a similarrepresentation showing the connection between the check-rower and theshakebar disconnected. Fig.4 is an elevation of the front guide for thewire from the position indicated by arrow Y, Fig. 1. A seed box of aplanter is shown at 1, a

shake bar at 2, a runner at3 and an end of a mtcmss bar of a planterat 1. The check row bracket 5 is shaped to fit the planter box, and itis secured thereto by bolt 6. Bar 7 is secured to the front end of thebracket and extended obliquely forward and outward. Bar 8 is fastened tothe rear end of the bracket and extended rearward and inward. On the extended end of each bar is a forked lever 9 and a bracket 10 carryingguide pulleys 11 and 12,

' which will be described in detailhereinafter.

The vertical shaft 13 has bearings in bracket 5. It is supplied at itslower end with a hori-L zontally extended rockarm, 15, which may beconnected with the shake bar 2 by means of rod 16, or in any othersuitable manner.

The pin 22 extends transversely through the shaft and projectstherefrom; and the shaft is held against longitudinal motion in itsbearings. The rock plate let'is mounted loosely on the shaft above thecross pin, and a downward extending sleeve of the plate has A- shapedrecesses adapted to receive the pin. The arm 17 is pivoted on thebracket at one end. It extends under the rock plate, and it has a hook,18, that extends over the flange of the plate. Lever 19 is also pivotedon the bracket at one end and its opposite end is hooked downward in amanner and for a purpose to be hereinafter explained. Link 21 connectsthe lever 19 with the arm 17 and provides means for, using the lever tothrow the rock plate in and out of clutch with the pin of the shaft. Rod27 connects one end of the rock plate with the forward forked lever, androd 28 connects the opposite end of the plate with the rear forkedlever. The forward end of bar 7 is supported by brace 25, which isfastened to the barand to the front cross bar of the planter. Thelocation of the planter seat, with relation to the check rower, is shownat 24:. The check row line 26 runs through the guide pulleys and theforked levers, as shown, and it is provided with knots by means of whichthelevers are thrown and motion imparted t0 the planting mechanism.

The opposite side of the planter is supplied with check row mechanismthe same as that shown and described, except that the arrange,- ment isreversed in order to carry the wire obliquely across the planter fromthe opposite direction. In other words, to use a com mon expression, thecheck row bars are rights and-lofts. I

As the planter moves forward a'knot on the the rear-forked lever andthrows it backward to its shown position, and each operation imparts adropping action to the planting mechanism."

While the check row line is used on one side of the planter thehooked-end 20 of lever 19, p

on that particular side, extends over the line in"a manner to hold it inthe rower, and the clutch recess of the rock plate receives the crosspin of the shaft and completes the connection between the forked leversand the shake bar.

When an end of the field is reached the hooked lever, 19, is raised tothe position shown in Fig. 3, thereby swinging it clear of the check rowline and raising the rock plate.

from contact with the cross pin of the shaft; and subsequently the lineis thrown off,.by detaching it from the rear guides by directmanipulation, and then raising it clearof the front forked lever andrear guide of thefrout pair of guides. This is done by the driver as hesits in his seat, that part of the line-adjacent to him being raisedhigh enough to effect the desired result, and when the wire is clearofthe rear guide of the front pair it will at once detachitself from thecheck rower. The planter may then be turned around, the line he placed Iin the check rower on the opposite side of the planter, and the hookedlever on that side be swung downward over the wire, in, theman nershown, and with the result that the rock plate on that side will beforced in clutch with the shaft that actuates the shake bar. This Willleave one side of the checkrower in en- As the front forked lever throwsthe rock plate in one direction and the throw of the rear forked leverreverses that direction, it will be seen that the plate may occupyeither of two positions when the wire is thrownoff,

and that it is aneven chance whether or not the shake bar and the clutchmember of the shaft will correspond tothe position of the rock shaftwhen the time foroperating the particular rock plate recurs.

If the parts should not properly coincide the inclined sides of theclutch recess of the rock plate will act on the pin to turn the shaft asthe plate is forced down by the motiouof the hooked lever and will movethe shake bar. to the position corresponding withithe forked levers ofthat particular side of the check rower; thereby making operativeconnection between the parts.

The manner of disconnectingithe line from the check rower, hereinbeforedescribed, is; made possible partly by the oblique arrangement of thecheck rower and the provisionof two leversadapted to be successivelyactuated by the same knot, and partly by the construction andarrangement'of. the guides for the wire, particularly the front ones.The first named peculiarity brings the line and the rear guides in easyreach of the driver as he sits on his seat, and the lastnamedpeculiarity enables a simple raising of the wire, by the hand ofthe driver, to disconnect the wire from the front guards.

The guides 11 and12 are both shown and described herein as pulleys, andsuch is in fact the preferred construction; but it is not essential to asatisfactory operation of the device that guide 11 should rotate. The.essential features of this part of the device are that the front guideshall, rotate on an approximately vertical pivot and have an upperflange, and that the other guide, of the front pair. of guides, shall beflangeless at its'upper end. shal bevefli r ubstanti l y and helli a n an a p ion'r vnih rear of the flanged pulley and outside the normalposition of the check row wire. It is desirable, moreover, that the rearpair of guides be constructed as described and placed in reversedpositions, as shown.

The forward pulley of the forward pair of guides-rotates to carry thewire, its flange holds the wire against upward displacement, and therear guide of the pair holds the Wire against outward displacement. Onthe other hand, the rear guide of the front pair offers no resistance tothe raising of the wire, in the manner specified, and when the Wire isonce clear of Such guide t swings ree. o a

straint and is discharged from t. the check he hoo ed l e 19 i-d netainins e wire in thecheck rower while the planteris. in operation, andit necessitates thedisen; gagement of the clutch mechanism prior tothrowing oi the wire, thus; makingihcertai-n that itwill not beattempted-to run theplauter. with both check rowers in connection; withe ke ba y k g he c e k ower rasspeeifie e 'r w e may pas Over he e box,as shownin the drawings, and the open:
